reflective floor effect
I am creating a 3-D animation with lights, cameras, and stills. I am wanting to create a “reflective floor effect.” This is to say that I would like reflections of the stills to be cast out from the bottoms of each. I have tried the mirror effect, and various other things but just can’t quite get it. Any ideas? Thanks.

AE doesn’t do raytracing. You have to duplicate your scene and flip it up-side-down.
Do a search on cow for “reflection”…. -
Yeah AE doesnt do that unless you fake it like the previous post stated. Here is a thread I started where I was trying to study Apple’s Front Row app.

I also have a zip file on my iDisk that you can get and take apart. BTW, I am on AE 6.0 pro, sorry my
update hasn’t came in yet, 🙁los

Thanks for responding folks. Lon, how can I get that file you referred to?

One cool thing that I’ve had some success with is using a backlight with the light transmission set up all the way. This allows a light to penetrate the object and project it onto a “floor” or reciever object. This looks alot like a reflection and has the added benefit of being able to project on multiple surfaces. Your rear light needs to be a spot light with shadows enabled.

Bear’s post is done in detail in the tut, “Using Projection Layers to create a gobos and projector type effects” by Rick Gerard, in the Comp (AEP included in the tut) “Advanced Projection (Final)”:
It’s really cool and I forgot about it untilI read Bear’s post.

I finished a project recently, wheere I made a seamless spinning ‘ring’ of images in 3D space with fake reflections which worked quite well in 3D except for twice in the ring where the reflection images that where behind the foreground images showed up in front cause of the way the ring was tilted. So I just lowered the opacity at that point in time so it wasn’t as noticable. The results were pretty good, sort of like apples front row. Here’s a screen shot:

As you can see, I used a camera with a very shallow depth of field. Let me know if you want more info on how I did it.

If you are on a Mac, you can just GO>iDisk>Other User’s iDisk and put in my .Mac name which is loitz and then the password is “sharing”. No quotation marks.
If you are on a PC. I don’t know how to get to it since I never tried. But Apple tells you PC guys to read this:

About a year late on the conversation, but while Apple’s reflective floor obsession is ten minutes away from being the new drop shadow, why not use another camera in the scene whose Y transform properties are inverted from the original camera – assuming a floor is your reflective surface. Then comp the view from your inverted camera underneath the original 3d view. Another possibility would be to duplicate the scene in a new comp, attach everything but the camera to a null object with scaleY at -%100 (assuming the reflective floor is at posY 0). Then comp behind the original – and apply levels, directional blur, etc. independently from the original.
